The answer is 139

because 5 x 8 = 40 and 9 x 11 is 99
and 40 + 99 = 139

If x^2 - 6xy = z - 9y^2, make x the subject of the formula
alukav5142 [94]

~~~~x^2-6xy=z-9y^2\\\\\implies x^2- 2\cdot x\cdot 3y + (3y)^2 - (3y)^2 = z-9y^2\\ \\\implies (x-3y)^2 -9y^2 = z-9y^2\\\\\implies (x-3y)^2 = z\\\\\implies x - 3y =\pm\sqrt z\\\\\implies x = 3y\pm\sqrt z

PLEASE HELP ME PLEASE!!!
dimaraw [331]

Answer:

Step-by-step explanation:

Let's just check something out before we continue to fill in the blanks.

The zeros are (x - 1) and (x -5)

y = (x - 1)(x - 5)            Remove the brackets.

y = x^2 - 6x + 5          Complete the square

y = (x^2 - 6x + 9) + 5 - 9

y = (x - 3)^2  - 4

So we have a minumum at (3, - 4)  Now we can go through the rest of the questions.

Part A

(1,0) and (5,0)

Part B

The vertex is (3, - 4) See the completed square above.

Part C

It's a minimum. It is the point between the two roots on the x axis. The vertex drops below the x axis.

Part D

The axis of symmetry goes through the x value of the minimum.

x = 3

The answers are all in parts A B C D. I leave you to figure out where to put them.  You should be able to do that.
